6-nitropyridine-2-carboxylic acid - Introduction
acid is an organic compound with the chemical formula C6H4N2O5. The following is a detailed description of the properties, uses, preparation and safety information of the compound:
Nature:
-Appearance: acid is yellow crystal.
-Melting point: About 238-240 ° C.
-Solubility: In common organic solvents (such as ethanol, dichloromethane, etc.) dissolve better, insoluble in water.
Use:
acid has multiple applications in chemical research and industrial production:
-It can be used as a starting material for organic synthesis and for the synthesis of other compounds.
-Because it contains a nitro functional group, acid can also be used as one of the raw materials for explosives.
Method:
The preparation of acid can be carried out by the following steps:
1. 2-bromopyridine was used as starting material and reacted with nitric acid under the catalysis of carbonate and alkali to obtain 6-nitro-2-bromopyridine.
2. React 6-nitro-2-bromopyridine with carbonate under acidic conditions to obtain chromium acid.
Safety Information:
-acidix is a potentially dangerous compound and should be handled with caution.
-It may cause irritation to the skin, eyes and respiratory system, so wear personal protective equipment (such as gloves, goggles and respiratory protection) during use.
-Use, store and handle the compound in accordance with relevant safety guidelines and regulations.
